I measured the protrusion of the splines before taking anything apart, knowing that my timing was good before I got in there.
That way I was able to set them back to the same place and torque all the bolts, before putting the Vanos back on.
With the splines protruding <0.25", there's plenty of room to get the Vanos back on, just like it came off.

You're sticking with the stock exhaust hub?
I had the "that won't happen to me" attitude because I don't track my car and rarely go over 5500 rpm, but sure as heck, mine broke.
Maybe from all the blip shifting I do while spending way too much of my remaining life in concertina traffic.
